ELEGOO Dental Castable: Green Burnout Resin for Dental Casting (1 kg)
Overview: ELEGOO Dental Castable is a 405 nm photopolymer burnout resin designed for printing casting patterns for dental crowns, bridges, and metal frameworks. It burns out cleanly with minimal ash residue, shrinks only 0.2–0.5%, and delivers a smooth surface finish with fine detail. Compatible with 405 nm LCD/MSLA and DLP printers. Available in a 1 kg bottle in translucent green.

What Is Dental Castable Resin Used For?
It replaces manual wax-up in the lost-wax casting workflow. You design the crown, bridge, or framework in your dental CAD software, print it in resin, invest it in the casting ring, and fire it in the furnace — the resin burns away completely, leaving a precise cavity into which the metal is cast. The result is a fully reproducible pattern, free from the inconsistencies of hand-carved wax, and you can print multiple cases on the same build plate at once.
Does It Leave Residue After Burnout?
This is the most critical property of any castable resin, and it's where this material excels: ELEGOO formulates it to burn out cleanly with minimal ash residue, leaving a clean mold cavity so castings come out free of inclusions and porosity from leftover material. For best results, prints must be thoroughly washed and fully post-cured before investing, and you should use an investment material and burnout cycle appropriate for resin castables (follow your investment manufacturer's guidelines).
How Accurate Is It?
With just 0.2–0.5% shrinkage and a rigid formulation, it holds margins, thin walls, and occlusal detail with excellent dimensional stability. The smooth surface finish reduces pattern finishing before investing and results in castings with better surface quality straight from the mold. Pairing it with a high-resolution printer (12K or 16K) will get you the most out of its fine-detail capability.
Is It Compatible with My Printer?
Yes — if your printer operates at 405 nm, which covers the vast majority of desktop LCD/MSLA and DLP printers: ELEGOO Mars and Saturn, Anycubic Photon, Creality Halot, Phrozen, and similar machines. It is not intended for SLA laser printers using a different wavelength or for closed systems with proprietary cartridges.

Usage Tips
-
Shake the bottle thoroughly before each use: it contains additives that can settle over time.
-
Print at 25–35 °C. If the resin feels too thick, warm the bottle in a water bath at 60–80 °C before pouring.
-
Dial in your exposure settings using ELEGOO's recommended parameters for your printer (available on their website), and always run a test print before starting real cases — crown margins are the first thing to reveal incorrect exposure.
-
Wash with isopropyl alcohol (IPA) or ethanol above 95% for at least 30 seconds and fully post-cure before investing: an under-cured print won't burn out as cleanly.
- Wear nitrile gloves and work in a well-ventilated area. Store the bottle tightly sealed, in a cool, dry place away from direct sunlight.
Who Is This For?
Designed for dental labs and clinics looking to move from hand waxing to printed patterns for crowns, bridges, and partial frameworks — as well as for jewelers working with lost-wax casting who need fine detail and a clean burnout. This is not an intraoral resin or a study model resin: its sole purpose is to serve as a sacrificial pattern that burns away completely.
Workflow: Print, Wash, Cure, and Cast
Print on your 405 nm resin 3D printer, wash and post-cure in a wash and cure station, remove supports, invest, and burn out. For the models you'll use to fit your castings, the ELEGOO Dental Model is the tough resin for working and restorative models, and the ELEGOO Dental Orthodontic is designed for thermoforming orthodontic models.

ELEGOO Dental Castable — Frequently Asked Questions
What is a castable resin?
A castable resin is designed to burn out completely in a casting oven. It's used as a pattern in the lost-wax casting process: the printed piece is invested, burned out, and leaves behind a cavity into which molten metal is cast.
Is it suitable for crowns and bridges?
Yes. It's specifically designed for crown, bridge, and dental metal framework patterns, with low shrinkage to ensure accurate casting fit.
Does it leave ash after burnout?
Very little. ELEGOO formulates it for a clean burnout with minimal residue, as long as the part has been properly washed and post-cured.
Can it be used in the mouth?
No. This is a castable pattern material, not a biocompatible resin approved for intraoral use.
Will it work with my ELEGOO, Anycubic, or Creality printer?
Yes, as long as it's a 405 nm LCD/MSLA or DLP printer — such as the ELEGOO Mars and Saturn series, Anycubic Photon, or Creality Halot.
What's the difference between this and the ELEGOO Dental Model and Dental Orthodontic resins?
The Castable resin is for patterns that are burned out in a furnace for metal casting. The Dental Model resin is for working and restorative models that are kept as-is, and the Dental Orthodontic resin is for orthodontic models used in thermoforming.
Can it also be used for jewelry?
Yes. Its clean burnout and fine detail reproduction make it equally well-suited for lost-wax casting jewelry patterns.
What exposure settings should I use?
Settings vary depending on your printer model and light source power. Run an exposure calibration test before printing real cases and dial in your settings from there.
How do I wash it?
Use isopropyl alcohol (IPA) or ethanol above 95%, for at least 30 seconds. This is not a water-washable resin.
Why is post-curing important?
A fully cured pattern is more dimensionally stable during investing and burns out more cleanly. An under-cured pattern may leave residue or warp.
How many cases can I get from a 1 kg bottle?
Crowns and bridges are small pieces, so a kilogram goes a long way. Actual yield depends on part size, support structure volume, and how many pieces you print per build plate.
